Guide you with what? just post what you have so far and explain (clearly and detailled) what is going wrong. There are plenty people here who are willing and able to help, no doubt.

Is there any particular reason to do this in Java? Do you already have Java expertise? Maybe you could do it more easily in a scripting language.

first of all i am comfortable with java,what i need to do is i need send some information from my PC to hardware(micro controller) through bluetooth,i am just struck with java bluetooth api which i am not getting proper tutorial.Can u please help me with tutorial link or any notes...
thanks in advance

Personally I've never used the Java Bluetooth libraries, so I can't help you, sorry, but I'm sure you can find whatever tutorials and samples exist on the web...
Hopefully someone else will be able to help.

You need to be more precise in where is your issue, because we do not see what have you done so far, where are you stuck at.
Here are few resources I used in past (nevertheless my experience with BT was always related to mobile devices using J2ME and now Android)
